The aim of this 10\u2010year randomized controlled trial was to compare peri\u2010implant soft and hard tissue parameters, esthetic ratings of, and patient\u2010reported satisfaction with immediate implant placement in postextraction sockets with buccal bony defects \u22655\u00a0mm in the esthetic zone versus delayed implant placement after alveolar ridge preservation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients presenting a failing tooth in the esthetic region and a buccal bony defect \u22655\u00a0mm after an extraction were randomly assigned to immediate (Immediate Group, <jats:italic>n<\/jats:italic>\u00a0=\u00a020) or delayed (Delayed Group, <jats:italic>n<\/jats:italic>\u00a0=\u00a020) implant placement. The second\u2010stage surgery and provisional restoration placement occurred 3\u00a0months after implant placement in both groups, followed by definitive restorations 3\u00a0months thereafter. During a 10\u2010year follow\u2010up period, marginal bone levels (primary outcome), buccal bone thickness, soft tissue parameters, esthetics, and patient\u2010reported satisfaction were recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean marginal bone level change was \u22120.71\u00a0\u00b1\u00a00.59\u00a0mm and \u22120.36\u00a0\u00b1\u00a00.39\u00a0mm in the Immediate Group and the Delayed Group after 10\u00a0years (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.063), respectively.

The question is if an intact buccal bone wall is necessary for immediate implant placement. A 10\u2010year study was performed in which 20 patients with a failing tooth in the frontal region of the upper jaw were treated with immediate implant placement and were compared with 20 patients in whom a more conventional treatment strategy was followed in which the failing tooth was first removed and the bone gap restored and the implant placed in a second step. After a 10\u2010year follow\u2010up period, it appeared that the bone around the implant was very stable, gums were healthy, and patients were very satisfied with the result. There was no difference between the two treatment procedures. Such results mean that professionals can discuss the procedure with the patient and apply the individual's preference.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jper.24-0251","type":"journal-article","created":{"date-parts":[[2024,8,12]],"date-time":"2024-08-12T02:18:21Z","timestamp":1723429101000},"page":"151-163","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Immediate single\u2010tooth implant placement in bony defect sites: A 10\u2010year randomized controlled trial"],"prefix":"10.1002","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1702-6031","authenticated-orcid":false,"given":"Henny J.
